Are these good?

These rules are untested, I just thought of them, but I think they would work pretty well.

The basic premise is you roll to hit before you fire. Rather than rolling the operator's skill, you roll a targeting computer's skill (1d10, probably). The computer can be attached to the weapon or in remote communication. Use normal to-hit mods (and you could even add an ECM "skill" that subtracts from the computer's). Less than use=no lock, equal to or greater than=lock. Once lock is achieved, you may fire. Projectile rolls its own skill (probably same as computer, maybe less), if 1 or less, lose lock and scatter, otherwise hit (ECM mods again). I don't know about maintaning targeting computer locks, maybe the same rules as for missiles firing.

Again, these are untested. I plan on using them in a battle I have coming up, if I do I'll let you know how it works. No idea about CP, I don't use them. This may be a way to increase the accuracy of heavy artillery/launchers.

If anyone has crticism or ways of streamlining this, please let me know. And if anyone actually uses it definitely let me know!

This should be in the Rulebook somewhere:

"Any problem on earth can be solved with the careful application of high explosives"
-Valkyrie (the movie)

I'm not sure how this would increase accuracy of anything projectile. Instead of a single UR, you have now introduced 2 UR's to fire the weapon, increasing the odds that you will miss or crit fail. I'm not sure why you wouldn't use normal rockets.

Except that he means that the skill roll now refers to the computer's ability to aim, not the minifig's, and because the computer is aiming prior, there result of a critical fail would probably in fact be reduced. Anyhow, I believe he's still only referring to a single roll.

Sure, the computer is now aiming, but the way it is written there is a skill check made after the aiming roll as well. That's two rolls and two chances to critically fail as opposed to just one chance. I'm not super with statistics, but it doesn't seem correct that you increase accuracy by also increasing chance.

Here's what I mean. I've got a computer with 1d10 skill aiming. For the sake of argument, the guided rocket is MKII with UR: 4. All things being equal, a lock chance of 0.70. 0.30 chance to miss or crit fail. The same computer is also the firing mechanism (and has the multitask skill I'm assuming or it would have to wait til next turn to fire...) and so rolls another 1d10 skill roll. This second roll has a 0.90 success rate and a 0.10 crit-fail rate. Unless I'm mistaken in my math (which I might be), That brings the rocket's statistical chance of hitting to 0.63, which is less accurate than just taking a single skill check with a minifig with skill 1d10.

The only advantage I'm currently seeing is that locking prior to firing could potentially save ammunition over time (which probably isn't insignificant given the relative price of explosives).

You could just have a targeting computer for x amount of cp that can target an object in range. For every turn the computer focuses on that object, subtract -1 UR to fire the rocket at the target.

Same here, could you explain a little better where's the advantage? The main effect I see is to slow down the firing rate.

I had really meant these to be used by big launchers, size 5+, with really high use ratings. My main thinking behind that was to keep from wasting ammo on misses (which, if you have explosives, and with an additional CP cost for the guidance system, can be helpful) and because the computer can have higher skill than a minifig (only heroes and such have 1d10 skill, most artillerists would be 1d6--and you could even give the computer a higher skill).

Also, with a long-range weapon that takes multiple turns to hit, a guided missile can follow the target (lock is to specific object, not place)

You can fire the same turn you get a lock. The second roll was meant to give the target a chance to break lock, something like this: "sir, they've locked onto us! Missiles inbound!!" "Evasive maneuvers, try to throw off their targeting!" (and, on second thought, unless it's fast and wildly evading or has massive ECM you can probably ignore the second roll-there's not much for a tank to do to avoid a missile).

Thanks for the input

This should be in the Rulebook somewhere:

You are thinking in Brikwussy style because it reduces destruction on the battlefield. A real Brikwarior would stil be pleased if al of his large ordenance and missiles would mis, as long as they stil bring epic destruction. He would even still be pleased if his misfired rounds would hit his own units.

Also, if you fire multiple missiles, each one has a higher chance to hit--in your example, Rev, the first is only a 63% chance, but every one after is 90% (and if the first misses, you don't lose your missile)

And crazyhorse, if a missile misses there's no guarantee it will cause destruction--it may hit nothing. Lots of shots in the same place also lets you kill the big things too--so my system does result in more death (and isn't it killing the biggest creations that gives the most satisfaction?).

Point taken legion, but the next consideration will be cost-effectiveness. Questions like how big the computer is/how big the creation with the computer is influences the size cost of the computer's skill. And then the computer or whoever is firing the missiles will need several levels of multitasking in order to actually fire more than one missile per turn per lock.

I think Arkbrik's design is the most elegant, simple, and effective so far.

Why I came up with this: I was going to attack an Imperial command bunker, and I thought I'd use that as the control center for a massive railgun launching these guided missiles (thus the reason for attacking it).

I do think Arkbrick's idea would work: skill roll to hit like normal, and the missile just kamikazes. I'll try it both ways and see which works.

I think Arkbrik's idea is just easier, too. If you wanted a Javelin rocket launcher or predator missile or whatever, just have them all set aside and when the minifig fires his launcher or the predator missile, put it on the table.
